Announcing OpenCode School!

A free, self-paced course that teaches you how to use OpenCode, the open-source AI coding agent.

No account required. No personal data collected. Free forever.

@jamesqquick it creates the workflow files, guides you through creating cloudflare api tokens if needed, configures secrets on the repo with the gh cli, etc

[Zeke Sikelianos @zeke]

I built an agent skill to help you set up automated preview deployments to Cloudflare for every GitHub pull request.

https://t.co/IzLzC6QP0y

[Zeke Sikelianos @zeke]

It uses GitHub Actions and the GitHub Deployments API to automatically create preview deployments whenever you open a pull request, and tear them down when you merge or close the PR.This allows you to test your changes in a live environment before shipping them to production.

I made this a skill because there's some nuance to getting these workflows right, and I do it often enough that I want to make the process repeatable.

Try it out and let me know if you hit any snags!

This might help (in the Cloudflare Browser Run case, at least):

> WebMCP requires Chrome beta features. We have an experimental pool with browser instances running Chrome beta so you can test emerging browser features before they reach stable Chrome. To start a WebMCP session, add lab=true to your /devtools/browser request.

Any WebMCP experts out there?

I'm trying to get agents to reliably auto-detect the presence of WebMCP support in my app, but they generally don't notice or use it unless I specifically mention it in my user prompt like "... and use WebMCP pretty please."

I've added content to the page, adding a console.log message, screen reader notes, and of course populating the `document.modelContext` object, but those aren't doing the trick.

Any ideas?

[Zeke Sikelianos @zeke]

@mattzcarey Haha you mean the CLI over MCP thing? Yeah. Hot take.

I'm just noticing personally that gh, glab, and a handful of skills are slowly taking over what used to be a config full of MCP servers.

[Zeke Sikelianos @zeke]

CLI > MCP

This thing actually works, and it's noticeably faster!

Yank the old Chrome Devtools MCP config out of your agent's JSON file and use this instead:

npx skills add zeke/faster-chrome-devtools-skill --global --all --yes

⚡️🐌⚡️ The Faster Chrome DevTools Skill is now even faster.

Instead of using DevTools MCP and the Puppeteer runtime, it now bundles a dependency-free Node.js client that speaks Chrome DevTools Protocol (CDP) directly over WebSocket.

Thanks to @mattzcarey for this awesome improvement! 🧡

Why a CLI instead of an MCP server?

1. Works anywhere. Any agent with a shell can use it. No MCP server to configure.

2. Full CDP protocol. MCP has high-level tools plus JS eval, but the CLI can call any Chrome DevTools method.

3. Leaner context. No more loading always-on tool schemas; the skill loads on demand and runs through your agent's shell.

4. No screenshot bloat. MCP inlines screenshots into model context, but the CLI writes them to a file and returns the path.

Notebook LM has gotten really good.

Dump a bunch of context into the chat, then generate a podcast, video, quiz, flash cards, etc.

And now there's a mobile app too.

And it's free.
